[origin: US4503312A] PCT No. PCT/JP82/00222 Sec. 371 Date Feb. 8, 1983 Sec. 102(e) Date Feb. 8, 1983 PCT Filed Jun. 9, 1982 PCT Pub. No. WO82/04413 PCT Pub. Date Dec. 23, 1982.Method of controlling resistance welding to obtain high quality welds in which the pressure between the electrodes (2a, 2b) holding the materials (1a, 1b) to be welded is controlled so that the resistance value between the two electrodes (2a, 2b) is a predetermined value, and the welding current is regulated so that the voltage between the electrodes is a predetermined value, and the time during which the welding current flows is controlled to a fixed period.
